Provided is a robotic device including: a body; an electronic computing device housed within the body; and at least two wheel suspension systems coupled with the body including: a first suspension system including: a frame; a rotating arm pivotally coupled to the frame on a first end and coupled to a wheel on a second end; and an extension spring coupled with the rotating arm on a third end and the frame on a fourth end, wherein the extension spring is extended when the wheel is retracted; and a second suspension system including: a base slidingly coupled with the frame; a plurality of vertically positioned extension springs coupled with the frame on a fifth end and the base on a sixth end; at least one set of paired magnets, with at least one magnet affixed to the frame and paired to at least one magnet affixed to the base.

IPC Classes  ?

  • B60G 3/26 - Means for maintaining substantially-constant wheel camber during suspension movement
  • B60G 21/05 - Interconnection systems for two or more resiliently-suspended wheels, e.g. for stabilising a vehicle body with respect to acceleration, deceleration or centrifugal forces permanently interconnected mechanically between wheels on the same axle but on different sides of the vehicle, i.e. the left and right wheel suspensions being interconnected
  • B60G 3/14 - Resilient suspensions for a single wheel with a single pivoted arm the arm being essentially parallel to the longitudinal axis of the vehicle the arm being rigid
